python pyqt5 QTableWidget 添加右键菜单

'''

【简介】

PyQT5的表格中支持右键菜单例子

'''

import sys

from PyQt5.QtWidgets import (QMenu, QPushButton, QWidget, QTableWidget, QHBoxLayout, QApplication, QTableWidgetItem,

QHeaderView)

from PyQt5.QtCore import QObject, Qt

class Table(QWidget):

if name == ' main ':

app = QApplication(sys.argv)

example = Table()

example.show()

sys.exit(app.exec_())

1. int QMap::size () const 可得 QMap的数据数目

2. 根据它可以建table: new QTableWidget(size, 1, this)

3. 遍历QMap:

QMap<QString, int>::const_iterator i = map.constBegin()

while (i != map.constEnd()) {

cout <<i.key() <<": " <<i.value() <<endl

++i

}

4. 把每一个iterator所指的那条数据变成一个QTableWidgetItem

QTableWidgetItem ( const QString &text, int type = Type )

5. 把QTableWidgetItem插入到对应的table行中

QTableWidget::setItem ( int row, int column, QTableWidgetItem * item )
